1.接口类
public interface TTS {
void playText(String playText);
void stopSpeak();
}
2.主要实现类
/**
* 系统播报类,部分手机不支持中文播报
*/
@SuppressLint("NewApi")
public class SystemTTS extends UtteranceProgressListener implements TTS, OnUtteranceCompletedListener {
private Context mContext;
private static SystemTTS singleton;
private TextToSpeech textToSpeech; // 系统语音播报类
private boolean isSuccess = true;
public static SystemTTS getInstance(Context context) {
if (singleton == null) {
synchronized (SystemTTS.class) {
if (singleton == null) {
singleton = new SystemTTS(context);
}
}
}
return singleton;
}
private SystemTTS(Context context) {
this.mContext = context.getApplicationContext();
textToSpeech = new TextToSpeech(mContext, new TextToSpeech.OnInitListener() {
@Override
public void onInit(int i) {
//系统语音初始化成功
if (i == TextToSpeech.SUCCESS) {
int result = textToSpeech.setLanguage(Locale.CHINA);
textToSpeech.setPitch(1.0f);// 设置音调，值越大声音越尖（女生），值越小则变成男声,1.0是常规
textToSpeech.setSpeechRate(1.0f);
textToSpeech.setOnUtteranceProgressListener(SystemTTS.this);
textToSpeech.setOnUtteranceCompletedListener(SystemTTS.this);
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
//系统不支持中文播报
isSuccess = false;
}
}
}
});
}
public void playText(String playText) {
if (!isSuccess) {
return;
}
if (textToSpeech != null) {
textToSpeech.speak(playText,
TextToSpeech.QUEUE_ADD, null, null);
}
}
public void stopSpeak() {
if (textToSpeech != null) {
textToSpeech.stop();
}
}
//播报完成回调
@Override
public void onUtteranceCompleted(String utteranceId) {
}
@Override
public void onStart(String utteranceId) {
}
@Override
public void onDone(String utteranceId) {
}
@Override
public void onError(String utteranceId) {
}
}
3.使用
SystemTTS systemTTS = SystemTTS.getInstance(getApplicationContext());
systemTTS.playText("你好,世界，我是小白");
